This paper presents a systematic model for the simulation and analysis of a power-shift transmission that features a dual-clutch design. The paper models the kinematics, dynamics and control of the transmission for the analysis of powertrain overall performance and shift transient characteristics. The model is implemented in an object-oriented software tool. Analytical formulations and look-up tables are both used for modeling of powertrain components. The vehicle system model is established by integrating the various components and subsystem models according to the transmission structure and control logic. As a numerical example, the model is used for a vehicle equipped with the power-shift transmission to simulate the speed follow-up over a standard EPA drive range and the wide open throttle position performance.

Abstract In this work we present a new software tool for helping students perform basic kinematic analysis using Internet. It allows students to model and analyze planar multibody systems with rigid bodies. Master objects that contain data and algorithms for modeling and analyzing rigid bodies and lower kinematic pairs have been developed following an object-oriented approach. The layouts of the objects are discussed and the way of instancing them for defining a model of a multibody system is described. The student can analyze interactively the model created in this way, using the software tool itself, or he can export it to the MAPLE code. From MAPLE the student can obtain, in an automatic way, numerical or closed-form solutions of the kinematic equations.

The development of business information systems has the communication gap that exists between business and software experts, because they live in their own well-defined and complex cultures. One place where this gap manifests itself is in the constant failure of software developers to fully capture the system requirements. Second example is the inability to exactly analyze and store business knowledge. In our experience, gathered during the last ten years, working on major software projects, not all system requirements are known at the start of the project and the customers expect that their discovery and refinement will form part of the project. Our solution of this dilemma is in the new methodology called BORM (Business and Object Relationship Modeling), which reuses the object-oriented approach known from the area of software engineering into the area of business process modeling. CraftCASE is the original Czech software tool supporting BORM. CraftCASE is developed to capture and analyze knowledge of process-based business systems. The integral part of the analysis using CraftCASE is object-oriented process diagram and process simulator.
